Nutrient pollution from agriculture and urban areas plus acid mine drainage (AMD) from legacy coal mines are primary causes of water-quality impairment in the Susquehanna River, which is the predominant source of freshwater and nutrients entering the Chesapeake Bay.

Your Land, Your Water: Using Research to Guide Conservation Practices on Local Farms in the Chesapeake Bay Watershed

Webber JS, Clune JW, Soroka AM, and Hyer KE ·
19 December 2023

Agricultural lands are an important part of the economy and heritage of the Chesapeake Bay watershed and are a focus of conservation activities. Streams and rivers around farms provide communities with drinking water and recreational opportunities, but these local benefits can be impaired by elevated nutrient and sediment concentrations.

Effects of point and nonpoint source controls on total phosphorus load trends across the Chesapeake Bay watershed, USA (Page 1)

Effects of point and nonpoint source controls on total phosphorus load trends across the Chesapeake Bay watershed, USA

Zhang Q, Bostic JT, Sabo RD ·
2024

Reduction of total phosphorus (TP) loads has long been a management focus of Chesapeake Bay restoration, but riverine monitoring stations have shown mixed temporal trends. To better understand the regional patterns and drivers of TP trends across the Bay watershed, we compiled and analyzed TP load data from 90 Non-Tidal Network stations using clustering and random forest (RF) approaches.

Restoring vegetation in degraded ecosystems is an increasingly common practice for promoting biodiversity and ecological function, but successful implementation is hampered by an incomplete understanding of the processes that limit restoration success. By synthesizing terrestrial and aquatic studies globally (2594 experimental tests from 610 articles), we reveal substantial herbivore control of vegetation under restoration.

2022 Maryland Coastal Bays Report Card (Page 1)

2022 Maryland Coastal Bays Report Card

Bill Dennison, Conor Keitzer, Nathan Miller, Alexandra Fries ·
24 October 2023

The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2022 Coastal Bays health. Coastal Bays health is defined as the progress of four water quality indicators (total nitrogen, total phosphorus, chlorophyll a, dissolved oxygen) and two biotic indicators (seagrass, hard clams) toward scientifically derived ecological thresholds or goals.

2023

From time immemorial, humankind has looked to the ocean for food and other useful products, for warnings of impending danger (e.g., storms and invaders), for inspi- ration, wonder, and beauty, and as a broad avenue for exploration, adventure, and commerce (see Chapters 1 and 3). Today, we watch the ocean more closely and care- fully than ever before. Globally, the ocean and its coasts affect human health and well-being in many ways, some positive, others negative (Sandifer et al., 2021a).
